## What is PaceForge?

PaceForge is your race-day brain. Turn any recent run into a complete game plan — predicted finish times, the exact training paces to hit, heart-rate zones, and a split-by-split pacing strategy — all computed on your device in seconds, with no account and no internet required.

Whether you're chasing your first 5K or a marathon PR, PaceForge gives you coach-grade answers without the subscription.

WHAT'S INSIDE
• Race Predictor — enter one result and see projected times for 5K, 10K, half, and marathon (Daniels' VDOT + Riegel models).
• Training Paces — your personal Easy, Marathon, Threshold, Interval and Repetition paces.
• Pace Calculator — instantly convert between pace, speed, time and distance.
• Heart-Rate Zones — five training zones from your age and resting HR (Karvonen, Tanaka).
• Race Plans — build an even or negative-split plan and get every kilometre/mile split for race day.
• Track Splits — lap-by-lap targets from 200 m to a mile.
• Treadmill Converter — turn an incline pace into its flat-road equivalent (Minetti grade-adjusted pace).
• Personal Records — keep your all-time bests and reuse them in every tool with one tap.

WHY RUNNERS LOVE IT
• Works offline — works on the start line, on a plane, anywhere. No signal needed.
• No account, no sign-up — your records and plans never leave your phone
• Science-based — Daniels' VDOT, Riegel, Karvonen and Minetti, not guesswork.
• Fast and focused — clean answers in seconds, no clutter.
• Kilometres or miles, light or dark, and 7 languages: English, Español, Français, Deutsch, Italiano, Português (BR), 日本語.
• Free to use, supported by ads.

Back up and restore your data anytime — it always stays yours.

Lace up. PaceForge does the math; you do the running.


## Version history (last 2 releases)

### 1.1 — 2026-09-19

PaceForge stays free thanks to ads. This update adds ad support across the app — a banner above the tab bar, native cards below your lists, and occasional full-screen ads between screens. They're frequency-capped, never interrupt onboarding, and every one can be closed right away.

• Ad privacy controls in Settings (where regulation requires them).
• Under-the-hood updates and polish.

Your records, plans and settings stay on your device, exactly as before.

### 1.0 — 2026-07-01

No release notes.
